Patent GB-426905-A (GB)
Title: Improved production of tubular artificial textile threads
IPC: D01D5/24
Filed: 1934-10-12
Abstract: In the production of tubular artificial fibres of less than 2 deniers from viscose solutions, coagulating baths containing sulphuric acid and sodium sulphate are used, and the concentrations of these coagulating agents indicated in Specification 255,527, [Class 2 (ii)], are increased by 20 per cent at least and preferably by 25--20 per cent for 1 denier filaments, and are increased on this basis for filaments having a titre greater or less than 1 denier by a quantity proportional to the difference between the titre of the filament and 2 deniers, the ratio between the sulphuric acid and the sodium sulphate remaining substantially constant.  Preferably the filaments are given a short path such as 25 centimetres or less in the coagulating bath.  In an example, viscose of specified ripeness and alkalinity, and containing sodium carbonate is spun into a coagulating bath containing sulphuric acid, sodium sulphate, and zinc sulphate, in proportions in accordance with Specification 255,527. Satisfactory filaments of 1 denier could not be obtained with this bath, although it is assumed to be satisfactory for filaments of 2 deniers.  The solution is then spun into a bath in which the proportions of sulphuric acid and sodium sulphate are increased by 27,6 per cent, and satisfactory tubular filaments of 1 denier are obtained.  A bath in which the proportions are increased by 13,8 per cent is found to give similar results for filaments of 1,5 deniers. The threads obtained have good suppleness, feel, and curl, and provide noncreasing fabrics. They may be obtained in the form of a sliver on a frame on which the sliver is spun and undergoes all the subsequent treatments as far as the final drying.  The sliver is cut to staple lengths. The softness and curl of the filaments may be varied by slight variation of the ratio of sulphuric acid to sodium sulphate. Specifications 163,817, [Class 2 (ii)], and 421,157 also are p  referred to.

Patent GB-133187-A (GB)
IPC: H02H3/30
Filed: 1918-10-17
Abstract: 133,187. British Thomson - Houston Co., and Wedmore, E. B. Oct. 17, 1918. Protective arrangements.-In an arrangement of the Merz-Price type, lack of balance between the balancing-transformers at the ends of feeders &c. is compensated for by providing on the relays or tripping-devices of the system additional coils excited by the current of the system (and producing forces proportional to the current of the system) tending to restrain the relays from operating. In the arangement shown in Fig. 1, the operating- windings 2 of the relays are connected in the pilot-wire system in series with the restraining windings 1, which are connected across the transformers 4. The relays are normally held in the operative position by the restraining-coils and may have a mechanical bias in the same direction. The effect of capacity currents in the pilot wires may be annuled to some degree by a condenser inserted across the transformers in series with the restraining-windings. Capacity currents may, however, be dealt with by a compensating-winding 7, Fig. 3, connected in series with a condenser 8 and in parallel with the restraining coil, as described in Specification 17177/10, to produce a magneto-motive force opposing that produced by the current in the operating winding. The restraining-windings may be connected, in series with the condenser and compensating-winding, across the transformer.

Patent GB-745080-A (GB)
Title: Improvements in or relating to the oiling of textiles
IPC: D06B1/02
Filed: 1953-06-19
Abstract: <PICT:0745080/IV(c)/1> In a textile oiling system, particularly for oiling wool which flows through a duct a control means ensures that the flow of oil to the oiling nozzles is discontinued if the flow of wool through the duct is stopped.  The Figure shows an oil control device for use with a wool oiling system of the types described in Specification 740,889 in which oil under pressure is sprayed from nozzles into the wool which moves through a suction wool duct.  A deflector member 2 which is pivoted at 3 hangs downwardly into the wool duct so that whilst wool is passing from right to left it is deflected to the left thus turning a cam 5 against a roller 6 to lift a lever 7 which is pivoted at 7a the height of the pivot being adjustable on a rod 18.  The lever 7 moves against the restraint of a spring 16 and a mercury switch 13 has contacts 14, 15 which control the operation of a warning light and oil flow control means respectively.  Thus when the lever 7 moves from its normal deflected position to the horizontal position if the flow of wool on the duct closes a warning light shows and the flow of oil to the nozzles is cut off.  One end of the lever 7 is coupled through link 8 to a bell crank 9 which is attached to the piston of a modified type of dash-pot 11.  This ensures that the movement of lever 7 from the inoperative to the operative position is effected rapidly as the valve on the dash-pot is opening, whereas the reverse movement can only take place slowly so that oil is always present at the nozzles if wool is passing in the duct.  Cam 5 is so shaped to prevent operation of the control system due to unevenness of wool flow in the duct.  In an alternative control system a light beam passes across the wool duct and falls on a photo-electric cell so that in the event of the flow of wool through the duct closing the oil supply is cut off.
